Example 1 with SchemaParseException

use of org.apache.avro.SchemaParseException in project nifi by apache.

the class RestSchemaRegistryClient method createRecordSchema.

private RecordSchema createRecordSchema(final JsonNode schemaNode) throws SchemaNotFoundException {
    final String subject = schemaNode.get(SUBJECT_FIELD_NAME).asText();

Example 5 with SchemaParseException
